Title: Add support for spell checking 

This PR adds an `webFrame.setSpellCheckProvider` API to set a provider for spell checking in input fields and text areas.

Example:

```javascript
require('web-frame').setSpellCheckProvider("en-US", true, {
spellCheck: function(text) {
return !(require('spellchecker').isMisspelled(text));
}
});
```
